Dr. Quinn is the lead author of a paper published in Advances in Group Processes.  The study explores whether the structure and diversity of prior repeated exchange settings affect future prosocial behavior outside of the structure, toward unmet ingroup or outgroup interactants. Results show that the structure and composition of a person’s repeated exchange network at time 1 affects how much they trust an unmet person at time 2, and that one type of prior exchange network structure in particular (reciprocal exchange) caused study participants to trust unmet outgroup strangers more than other prior exchange structures. These experimental findings imply that the structure of prior environments can shape the way people interact with and the degree to which they trust others – even outgroup others – in the future.
